Analyze Copilot CLI history and generate personalized instructions

Drive the local vardoger CLI to read the user's GitHub Copilot CLI conversation history, extract behavioral patterns, and write a personalization block into ~/.copilot/copilot-instructions.md.

How it works

vardoger prepares the history in batches. You (the assistant) summarize each batch for behavioral signals, then synthesize all summaries into a final personalization. vardoger writes the result, fenced by <!-- vardoger:start --> / <!-- vardoger:end --> markers so any hand-authored rules in the same file are preserved.

Sandbox note (read before running any command)

vardoger reads and writes files outside the current workspace:

  • Reads Copilot CLI history from ~/.copilot/session-state/.
  • Writes a checkpoint state file to ~/.vardoger/state.json (created on first run).
  • Writes the final personalization to ~/.copilot/copilot-instructions.md.

When the host asks to approve a vardoger command, grant it write access beyond the workspace. Otherwise the first vardoger prepare call will fail with PermissionError: ... ~/.vardoger/state.tmp because the sandbox blocks writes outside the current working directory.
